A new line of straight waveguide sections operates in the frequency range of 5.85 to 110 GHz and in 13 waveguide bands from C- to W-Band. Typical applications include test benches, instrumentation, MILCOM, SATCOM, telecom, radar, and high-efficiency RF/microwave transmission networks. This new line consists of 61 models that are available in sizes ranging from WR-10 to WR-137. These waveguide straights deliver VSWR as low as 1.03:1 and are available in section lengths from 3 to 12”. They are made of either painted copper alloy or gold-plated, oxygen-free hard copper (OFHC), and feature UG-, CPR-, and UBR-style flanges.
